Slipstream is clean and contemporary handcrafted glass. Besa's easy-to-use bayonet mount secures the glass diffuser to the aluminum fitter with a "twist & lock" action. Our White Damask glass is an art deco nouveau in handcrafted glass. The background is painted in white on the inside, while the outer surface is etched so the pattern shows as frosted. This hand-blown glass is acid etched clear on the outside surface. The process of etching creates an un-textured, satin finished. The lit glass has a subtle yet functional design.
